Hi,

Sorry to bother you again. This time it's Android Studio.

Compiling using Android Studio with ndk 22.1.7171670 or 23.1.7779620 will throw error:
half.hpp:4576:4: error: cannot use 'throw' with exceptions disabled

Setting the flag -DHALF_ERRHANDLING_FLAGS=0 doesn't help. Did I miss anything?

Thank you for your time!

Best Regards,

  Hello,
  
  That wouldn't be the HALF_ERRHANDLING_FLAGS macro, rather than the
  HALF_ERRHANDLING_THROW_... macros, as explained in the documentation on
  http://half.sourceforge.net/. However, all the automatic error handling
  features already are disabled by default, so this won't help you. Your
  problem likely is the function fethrowexcept, which also works without
  automatic error handling and contains throw statements.
  
  Unfortunately it seems there really is no other way around it than for you
  to manually comment out or remove these throw statements from the function
  in your local version of the half.hpp file. Exception handling has been a
  standard C++ feature for decades and I can't really add options for
  disabling it just because some exotic platforms decide they don't properly
  support standard C++.
  
  Regards,
  Christian Rau

    Hi,
    
    Thank you for your reply. Turns out using clang-12 on linux with -fno-exceptions produce similar error. AFAIK Android NDK is using clang for their compiler.
    
    on my machine clang --version says:
    Ubuntu clang version 12.0.0-3ubuntu1~20.04.3
    
    Thank you for your time.
